Persoonia micranthera, commonly known as the small-flowered snottygobble,[2] is a species of flowering plant in the family Proteaceae and is endemic to a restricted area in the south-west of Western Australia. It is a low-lying to prostrate shrub with branchlets that are hairy when young, spatula-shaped to lance-shaped leaves with the narrower end towards the base, hairy yellow flowers borne in groups of four to fifteen, and smooth, oval fruit.
Description
[edit]Persoonia micranthera is a low-lying to prostrate shrub that typically grows to a height of 10–40 cm (3.9–15.7 in) with thin bark and branchlets that are hairy in their first year. The leaves are spatula-shaped to lance-shaped or egg-shaped with the narrower end towards the base, 40–80 mm (1.6–3.1 in) long and 8–30 mm (0.31–1.18 in) wide. The flowers are arranged in groups of four to fifteen along a rachis 10–60 mm (0.39–2.36 in) long on the ends of branchlets, each flower on a pedicel 2.5–8 mm (0.098–0.315 in) long. The tepals are yellow, hairy on the outside, 10.5–14 mm (0.41–0.55 in) long. Flowering occurs from February to March and the fruit is a smooth drupe.[3][4][5][6]
Taxonomy
[edit]Persoonia micranthera was first formally described in 1994 by Peter Weston in the journal Telopea from specimens he collected on the summit of Bluff Knoll in 1980.[5][7]
Distribution and habitat
[edit]Small-flowered snottygobble grows as an understorey shrub in thicket vegetation at high altitudes on peaks in the eastern Stirling Range.[4] In 2007 five populations were known, two with fewer than ten mature plants, two with fewer than one hundred and two with more than one hundred individuals.
Conservation status
[edit]This geebung is listed as "endangered" ander the Australian Government Environment Protection and Biodiversity Conservation Act 1999, as "Threatened Flora (Declared Rare Flora — Extant)" by the Department of Environment and Conservation (Western Australia)[6] and an Interim Recovery Plan has been prepared.[8] The main threats to the species include Phytophthora cinnamomi causing dieback, inappropriate fire regimes, trampling and grazing by local fauna.[8][9]
